Display apparatus and display method

Abstract

The present invention relates to a display apparatus and a display method that enable multiple users to view high resolution moving images from various viewing points of the users. A light-control screen 25 is rotated, and projectors 21 1 to 21 N irradiate the screen 25 from various directions with light rays corresponding to image data captured from those directions. In this case, when the forward direction of the light-control screen 25 is aligned with the projecting direction of one of the projectors 21 n , an image corresponding to light rays emitted from the projector 21 n is displayed on the light-control screen 25 . The present invention may be applied to a display apparatus for displaying images.

1 . A display apparatus which receives light rays to display images corresponding to the light rays, comprising:
 a diffusing plate which diffuses received light rays to display images corresponding to the light rays; and   an optical filter that transmits the light rays diffused by the diffusing plate in a predetermined direction,   wherein the diffusing plate diffuses the received light rays through the optical filter.   
   
   
       2 . The display apparatus according to  claim 1 , wherein the optical filter is disposed over the diffusing plate. 
   
   
       3 . The display apparatus according to  claim 1 , wherein the displayed images are displayed only on a side opposite to a side of the diffusing plate on which the light rays are incident. 
   
   
       4 . A display method which displays images according to received light rays comprising the steps of:
 diffusing received light rays by a diffusing plate to display images corresponding to the light rays; and   transmitting the diffused light rays by an optical filter in a predetermined direction, wherein the received light rays are diffused through the optical filter.   
   
   
       5 . A display apparatus comprising:
 a screen which receives light rays to display images corresponding to the light rays;   wide-angle light-emitting means for emitting the light rays corresponding to the images at wide-angles; and   reflecting means for reflecting the light rays emitted from the wide-angle light-emitting means toward the screen.   
   
   
       6 . The display apparatus according to  claim 5 , further comprising:
 driving means for rotating the screen around or on a predetermined rotational axis thereof.   
   
   
       7 . The display apparatus according to  claim 6 , wherein an optical axis of the wide-angle light-emitting means is aligned with the predetermined rotational axis of the screen. 
   
   
       8 . The display apparatus according to  claim 5 , wherein a plurality of reflecting means are disposed around the screen 
   
   
       9 . A display method comprising the steps of:
 receiving light rays on a screen to display images corresponding to the light rays;   emitting the light rays corresponding to the images at wide-angles; and   reflecting the light rays emitted at the wide-angles toward the screen.
